Experiments have shown the feasibility of new composite electrodes ECP(Ox)
resulting from the dispersion of nanoparticles of a metal oxide (Ox) into a
n electrically conductive polymer (ECP). In this preliminary work, Ox was a
spinel mixed valence oxide of copper and manganese, Cu1.4Mn1.6O4, and ECP
was polypyrrole. The intimate mixing of the two materials modified neither
the ECP charge-transfer and transport behavior nor the electrocatalytical a
ctivity of the oxide. These composite electrodes exhibited a remarkable sta
bility, even in acidic media, in contrast to noncomposite electrodes of the
same oxide. (C) 2000 The Electrochemical Society. S1099-0062(99)12-039-X.
